Y Combinator Companies (2005-2026) — Analysis

Key Findings

YC scaled from 9 companies (2005) to a peak of 727 (2021) before pulling back — 2022-2023 saw a 32% contraction from the peak
B2B dominates with 2,876 companies (50.5%), more than Consumer, Healthcare, and Fintech combined
Median team size is just 6 people, but the mean is 48 — a long tail driven by 74 companies with 500+ employees
Pre-2010 batches have lost over 80% of companies to shutdowns or acquisitions; the 2005 cohort has zero active companies
The 2005-2012 vintages produce "top companies" at 6-11% rates vs. under 1% for post-2018 batches — selecting fewer companies correlated with higher hit rates

Overview

5,690 companies funded across 48 batches from 2005 to 2026
69% are still active; 18% are inactive (dead); 13% were acquired; 0.4% went public
B2B dominates at 51% of all companies, followed by Consumer (15%) and Healthcare (12%)
San Francisco accounts for 37% of all YC companies by headquarters city
The median YC company has a team of 6 people
